Overview
491765 — 40A aR 14×51 Semicon Fuse+STRIKER, an ar semiconductor fuse link by DF Electric.
RAPIDPLUS aR high speed fuse links for semiconductors RAPIDPLUS aR fuses are Intended for clearing short-circuits, designed and manufactured to have very low I2t values with reduced arc voltages guaranteeing optimum semiconductor protection. Semiconductor fuse-links designed for protection of semiconductors (diodes, thyristors, triacs, etc) used in power rectifiers, UPS, converters, motor drives, soft starters, solid state relays, photovoltaic inverters, welding inverters and any application where semiconductor protection is required. For use with fuse holder incorporating a micro switch for remote "fuse blown" indication table.
Key specifications: rated current 40 A; breaking capacity 200 kA; rated voltage 690 V; 14 × 51 mm; to IEC/EN 60269-1, IEC/EN 60269-2.
